Actually, if "pre-Proto-Germanic" seems odd and perhaps redundant, it's not my fault; linguistics uses such terms. But I want to discuss the origin of the Germanic languages. Given the evidence of later migration from the south during the Nordic Bronze Age, combined with numerous loanwords from Proto-Celtic into the Germanic languages, I've concluded that the Germanic languages are not descended from one of the original Indo-European languages spoken in Scandinavia by the descendants of the Battle-Axe People. Material continuity is low.
